Add a developer hint log message for when RLIMIT_AS is the culprint in startup failure.

Add a developer hint log message for when RLIMIT_AS is the culprint in startup failure.

Tested w/ pending plugin-side CL http://codereview.chromium.org/10823019/ via:

bash -c 'ulimit -v 1000000;  /mm/bsy/chromium/chromium64.git0/src/out/Release/chrome --user-data-dir=/tmp/udd'

and trying to run Duke Nukem in NaClBox and seeing the log messages
show up in the JavaScript console.

BUG= http://code.google.com/p/nativeclient/issues/detail?id=2776
TEST= manual, requires a pending plugin CL.

If we do a lot of these user-facing messages, we may be asked at some point to
deal with localization. (no change required)

Thinking a bit more; will this work inside the SUID sandbox?

[bsy, 2012-07-25 20:39:20]

yes.  i run chrome w/ CHROME_DEVEL_SANDBOX set to
/opt/google/chrome/chrome-sandbox and it's working fine.
